("W" or the "Company")
High Grade Assay Results Continue at La Parrilla Tungsten Project
Significant intersections include 32 metres at 0.55% WO3
W Resources (AIM:WRES), formerly Caspian Holdings plc, is pleased to provide the latest update on drilling at its La Parrilla tungsten project, located in southwest Spain, in which it has an option to purchase a 100% interest.
The Company has received assay results for core holes 3 and 4 in the La Parrilla extension drilling programme, in which results from hole 4 were exceptional including 32 metres at 0.55% Tungsten Trioxide (WO3), five-times the average grade of the current La Parrilla resource. Hole 4 was drilled to a depth of 382.50m, 470m northwest of the main ore body and continues the series of strong results from the extension drilling programme.
Hole 3 assays were also positive with a combined 40 metres at an average of 0.2% WO3over 106 m to 170m - twice the current resource grade.
W has now completed six holes on its extension drilling programme with assays received on holes 1-4.
The full weighted averaged results of hole 4 and hole 3 are shown in the table below:

The weighted average grades have been calculated for intersections through
mineralised envelopes defined by quartz veining and no cut off grade has been used.
Mr Michael Masterman, Chairman of W Resources commented: "Given the success of the extension programme, W expects to complete another 4-6 holes in a grid pattern around holes 1-6 with the objective of defining a significant increase in both the grade and the tonnage of the La Parrilla mine resource."
In other developments, approval of the La Parrilla tailings project continues with key environmental approval documents now in place. As previously advised, the Company expects approval of the tailings in Q3 2012.

About La Parrilla
The La Parrilla project site is situated in the Extremadura region of southwest Spain, in the Provinces of Caceres-Badajoz, approximately 310 km southwest of Madrid. The site is accessed directly from the highway along a 3km asphalt road and is serviced by electricity and water. The project comprises a tungsten mine and a tungsten tailings project. The historic mine resource estimated by SRK in 2008 is 36.0m tonnes at 0.09% WO3 making it one of the largest tungsten deposits in the western world.
The technical design of the La Parrilla tailings project has now been finalised and approval documents submitted to the mining authorities. All approvals are expected to be granted by the end of Q3 2012. Annual plant feed will be 330,000 tonnes and annual production is anticipated to be 28,000 MTU Tungsten (W) and 26 tonnes Tin (Sn), which will deliver over €7million per annum in revenue at current tungsten and tin prices. The tailings project is expected to be in production in H2 2013.
The price of tungsten has increased rapidly over the last 3 years by more than double. The La Parrilla tailings deposit and tungsten mine development offer a low cost, high margin resource development opportunity for W Resources.
Sampling, Assaying and Quality Assurance / Quality Control (QA/QC) Measures
Drill sample intervals are reported as metres (m) down hole. True widths of mineralised intersections have been calculated assigning an average dip of the mineralised zones of 40º for hole IP-04 and 45º for hole IP-03. All drill core is transported by the Company personnel from drill site to a nearby secure storage facility for logging, by an experienced geologist, and sampling. The core is halved using a rotary diamond blade core saw, with one half of the core sent for analysis, while the other half is retained in the core boxes for reference. Sampling is mainly carried out over two metre intervals.
All half-core samples are sent for preparation to ALS Minerals facility in Seville (Spain). The resulting pulps are shipped to their laboratory in Vancouver (Canada) for assay using the ME-MS81 method (38 elements by lithium borate fusion and ICP-MS). Samples exceeding the upper detection limit (10,000 ppm W) are re-assayed by the lithium borate fusion and XRF determination ME-XRF10 method. Tungsten assays are reported by ALS Minerals as W and converted to WO3 using a factor of 1.26108.
Reference samples (blanks, duplicates and certified standards) are routinely inserted in each sample batch as quality control measure in addition to the laboratory's own internal QA/QC standards and duplicates.
